12.4. GTP Command Reference

This command creates a text description stored in the configuration file for a configuration context.

The description command associates a text string with a configuration context to help identify the context in the configuration file.

The no form of this command removes any description string from the context.

This command enables the context to configure subscriber management entities. A subscriber is uniquely identified by a subscriber identification string. Each subscriber can have several DHCP sessions active at any time. Each session is referred to as a subscriber host and is identified by its IP address and MAC address.

All subscriber hosts belonging to the same subscriber are subject to the same hierarchical QoS (HQoS) processing. The HQoS processing is defined in the sub-profile (the subscriber profile). A sub-profile refers to an existing scheduler policy (configured in the config>qos>scheduler-policy context) and offers the possibility to overrule the rate of individual schedulers within this policy.

Because all subscriber hosts use the same scheduler policy instance, they must all reside on the same complex.

This command enables the context to configure WLAN Gateway parameters.

This command configures the maximum number of GTP sessions to be held while their UE are disconnected.

The no form of the command reverts to the default.

This command creates a new mobile gateway profile or configures an existing mobile gateway profile.

Mobile gateway profile is used to configure signaling interface between WLAN-GW and mobile gateway (PGW or GGSN) and GTP related signaling parameters per mobile gateway.

The no form of the command removes the profile name from the configuration.

This command enables the context to configure charging characteristics.

This command configures the charging characteristics for home UE.

This command configures the charging characteristics for roaming UE.

The no form of the command removes the bit value from the configuration.

This command enables the context to configure communication with a GGSN Mobile Gateway.

This command enables the context to configure QoS for a GGSN Mobile Gateway.

This command configures the Aggregated Maximum Bit Rate (AMBR) to be sent in the APN AMBR IE. The contents of this IE can be overridden by RADIUS or report-rate mechanisms. If those mechanisms specify a partial value, such as only specifying the down-link parameter, the other value is picked up from the ambr configuration.

For GTPv1, the no form of the command implies that the IE will not be sent. If a partial value is received from another source, the missing value will use the following defaults:

For GTPv2, the no form of the command reverts to the default of 10000 kbps up-link and 20000 kbps down-link.

The command configures the allocation/retention priority to be used in the GTP messages as QOS IE (for a Gn interface) or Bearer QOS (for an S2a/S2b interface).

The no form of the command reverts to the default.

This command configures the down-link bitrate in Kbps to be used in the GTP messages.

The no form of the command reverts to the default.

This command configures the up-link bitrate in Kbps to be used in the GTP messages.

The no form of the command reverts to the default.

This command enables the context to configure communication with a Packet Data Network Gateway.

This command configures the QoS Class Identifier (QCI) to send in the Bearer Level QoS IE in GTP messages on the S2a/S2b interface.

The no form of the command reverts to the default.

This command specifies the signaling interface between the WLAN-GW and the mobile gateway (PGW or GGSN).

The no form of the command reverts to the default value.

This command configures the value to put in the IP header’s TTL field for GTP control messages.

The no form of the command reverts to the default value.

This command configures Echo-Request messages.

The no form of the command reverts to the default values.

This command configures the retry-count and response-timeout for GTP messages.

The no form of the command reverts to the default values.

This command configures the Information Element to use for the Protocol Configuration Options.

The no form of the command reverts to the default value.

This command specified the python-policy for MGW profile packets sent/received on the group interface

The no form of the command removes the policy name from the configuration.

This command configures the default Radio Access Type (RAT) signaled during GTP setup. RAT is the underlying physical connection method for a radio-based communication network. This can be overridden by RADIUS.

The no form of the command reverts to the default value.

This command enables reporting the WLAN location or cellular location of the UE in the signaling interface (S2a or Gn) between wlan-gw and mobile gateway (PGW or GGSN).

The no form of the command disables location reporting.

This command configures , in seconds, the time that a GTP session context is held after the corresponding User Equipment is disconnected. If the same User Equipment re-connects to this system before this time has elapsed, its GTP session context is re-used. When the timer expires, the GTP session context is cleared.

The no form of the command reverts to the default.

This command configures the Operator Identifier part (MCC and MNC) of the APN.

The no form of the command removes the values from the profile.

This command configures the Network Identifier part of the APN.

The no form of the command removes the string from the configuration.

This command configures the mappings of MGW IP address and GTP profile.

This command specifies the address.

The no form of the command removes the parameters from the configuration.

This command configures the PDP type to be signaled in GTP, determining which addresses are requested from the P-GW/GGSN and which hosts are set up afterwards. This can be overridden by RADIUS. If the ipv4v6 keyword is used, the P-GW/GGSN can fall back to either IPv4 or IPv6.

The no form of the command reverts to the default configuration.

This command displays GTP session information.

This command displays GTP statistics information.
